## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model A300 B4-600 and A300 B4-600R series airplanes, and all Model A300 F4-605R airplanes. The existing AD currently requires repetitive inspections to detect cracks of certain attachment holes, installation of new fasteners, follow-on inspections or repair if necessary, and modification of the angle fittings of fuselage frame FR47. This proposed AD would revise certain inspection thresholds and intervals. This proposed AD would also add inspections to detect cracks of additional attachment holes. This proposed AD is prompted by reports of cracks found before the inspection thresholds in the existing AD and cracks found in nearby areas not inspected by the existing AD. We are proposing this AD to prevent fatigue cracking of the forward fitting of fuselage frame FR47, which could result in reduced structural integrity of the frame.
